2021-09-10dt-bindings: More use 'enum' instead of 'oneOf' plus 'const' entriesRob Herring
'enum' is equivalent to 'oneOf' with a list of 'const' entries, but 'enum' is more concise and yields better error messages. Fix a couple more cases which have appeared.

Otherwise, depending on the placement of the ID map, kernel-VA to hyp-VA translations may produce addresses that either conflict with other HYP mappings or generate addresses outside of the 52-bit addressable range. - Instruct kmemleak not to scan the memory reserved for kdump as this range is removed from the kernel linear map and therefore not accessible. * tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: arm64: kdump: Skip kmemleak scan reserved memory for kdump arm64: mm: limit linear region to 51 bits for KVM in nVHE mode

2021-09-10fsnotify: fix sb_connectors leakAmir Goldstein
Fix a leak in s_fsnotify_connectors counter in case of a race between concurrent add of new fsnotify mark to an object. The task that lost the race fails to drop the counter before freeing the unused connector. Following umount() hangs in fsnotify_sb_delete()/wait_var_event(), because s_fsnotify_connectors never drops to zero.

2021-09-10of: property: Disable fw_devlink DT support for X86Saravana Kannan
Andre reported fw_devlink=on breaking OLPC XO-1.5 [1]. OLPC XO-1.5 is an X86 system that uses a mix of ACPI and OF to populate devices. The root cause seems to be ISA devices not setting their fwnode field. But trying to figure out how to fix that doesn't seem worth the trouble because the OLPC devicetree is very sparse/limited and fw_devlink only adds the links causing this issue. Considering that there aren't many users of OF in an X86 system, simply fw_devlink DT support for X86.

2021-09-10perf symbol: Look for ImageBase in PE file to compute .text offsetRemi Bernon
Instead of using the file offset in the debug file. This fixes a regression from 00a3423492bc90be ("perf symbols: Make dso__load_bfd_symbols() load PE files from debug cache only"), causing incorrect symbol resolution when debug file have been stripped from non-debug sections (in which case its .text section is empty and doesn't have any file position). The debug files could also be created with a different file alignment, and have different file positions from the mmap-ed binary, or have the section reordered. This instead looks for the file image base, using the corresponding bfd *ABS* symbols. As PE symbols only have 4 bytes, it also needs to keep .text section vma high bits.

2021-09-10drm/i915: Use Transparent Hugepages when IOMMU is enabledTvrtko Ursulin
Usage of Transparent Hugepages was disabled in 9987da4b5dcf ("drm/i915: Disable THP until we have a GPU read BW W/A"), but since it appears majority of performance regressions reported with an enabled IOMMU can be almost eliminated by turning them on, lets just do that. To err on the side of safety we keep the current default in cases where IOMMU is not active, and only when it is default to the "huge=within_size" mode. Although there probably would be wins to enable them throughout, more extensive testing across benchmarks and platforms would need to be done. With the patch and IOMMU enabled my local testing on a small Skylake part shows OglVSTangent regression being reduced from ~14% (IOMMU on versus IOMMU off) to ~2% (same comparison but with THP on).

2021-09-10io_uring: fix off-by-one in BUILD_BUG_ON check of __REQ_F_LAST_BITHao Xu
Build check of __REQ_F_LAST_BIT should be larger than, not equal or larger than. It's perfectly valid to have __REQ_F_LAST_BIT be 32, as that means that the last valid bit is 31 which does fit in the type.

2021-09-10drm/ttm: Fix a deadlock if the target BO is not idle during swapxinhui pan
The ret value might be -EBUSY, caller will think lru lock is still locked but actually NOT. So return -ENOSPC instead. Otherwise we hit list corruption. ttm_bo_cleanup_refs might fail too if BO is not idle. If we return 0, caller(ttm_tt_populate -> ttm_global_swapout ->ttm_device_swapout) will be stuck as we actually did not free any BO memory.

2021-09-09bootconfig: Rename xbc_node_find_child() to xbc_node_find_subkey()Masami Hiramatsu
Rename xbc_node_find_child() to xbc_node_find_subkey() for clarifying that function returns a key node (no value node). Since there are xbc_node_for_each_child() (loop on all child nodes) and xbc_node_for_each_subkey() (loop on only subkey nodes), this name distinction is necessary to avoid confusing users.

2021-09-09tracing/boot: Fix trace_boot_hist_add_array() to check array is valueMasami Hiramatsu
trace_boot_hist_add_array() uses the combination of xbc_node_find_child() and xbc_node_get_child() to get the child node of the key node. But since it missed to check the child node is data node or not, user can pass the subkey node for the array node (anode). To avoid this issue, check the array node is a data node. Actually, there is xbc_node_find_value(node, key, vnode), which ensures the @vnode is a value node, so use it in trace_boot_hist_add_array() to fix this issue.

2021-09-09cifs: properly invalidate cached root handle when closing itEnzo Matsumiya
Cached root file was not being completely invalidated sometimes. Reproducing: - With a DFS share with 2 targets, one disabled and one enabled - start some I/O on the mount # while true; do ls /mnt/dfs; done - at the same time, disable the enabled target and enable the disabled one - wait for DFS cache to expire - on reconnect, the previous cached root handle should be invalid, but open_cached_dir_by_dentry() will still try to use it, but throws a use-after-free warning (kref_get()) Make smb2_close_cached_fid() invalidate all fields every time, but only send an SMB2_close() when the entry is still valid.

2021-09-09arm64: mm: limit linear region to 51 bits for KVM in nVHE modeArd Biesheuvel
KVM in nVHE mode divides up its VA space into two equal halves, and picks the half that does not conflict with the HYP ID map to map its linear region. This worked fine when the kernel's linear map itself was guaranteed to cover precisely as many bits of VA space, but this was changed by commit f4693c2716b35d08 ("arm64: mm: extend linear region for 52-bit VA configurations"). The result is that, depending on the placement of the ID map, kernel-VA to hyp-VA translations may produce addresses that either conflict with other HYP mappings (including the ID map itself) or generate addresses outside of the 52-bit addressable range, neither of which is likely to lead to anything useful. Given that 52-bit capable cores are guaranteed to implement VHE, this only affects configurations such as pKVM where we opt into non-VHE mode even if the hardware is VHE capable. So just for these configurations, let's limit the kernel linear map to 51 bits and work around the problem.

2021-09-09thermal/drivers/qcom/spmi-adc-tm5: Don't abort probing if a sensor is not usedMatthias Kaehlcke
adc_tm5_register_tzd() registers the thermal zone sensors for all channels of the thermal monitor. If the registration of one channel fails the function skips the processing of the remaining channels and returns an error, which results in _probe() being aborted. One of the reasons the registration could fail is that none of the thermal zones is using the channel/sensor, which hardly is a critical error (if it is an error at all). If this case is detected emit a warning and continue with processing the remaining channels.

2021-09-09thermal/drivers/intel: Allow processing of HWP interruptSrinivas Pandruvada
Add a weak function to process HWP (Hardware P-states) notifications and move updating HWP_STATUS MSR to this function. This allows HWP interrupts to be processed by the intel_pstate driver in HWP mode by overriding the implementation.
